Hi Vince,
The price for the board is in USD (as this is what is accepted by the PCB house also) im prity sure Paypal will sort the conversion but i usually just leave any funds with paypal in USD anyways, so there shouldnt be any conversion at the end of the day for the purchaser. You are quite correct in saying that shipping could end up being expensive. if there are a few guys who would like them in the US/Canada it may be cheaper to ship a few boards to one of you and then one can distribute from there at a cheaper price (i love the US postal system.. quick and cheap compared to NZ). most likely ill have to DHL or Fedex it. NZ Post website is a bit of a PITA to be honest and not always accurate. thats why ill go take the package and get the actual cost from the office itself closer to shipment date.
